A. further object is to provide a carrier section coupling composed ofmembers 'which shell be interchengeable end capable et eppiicetion toeither end of a carrier.

The invention consists generally in various constructions andcombinations, ell as hereinafter described and particularly pointed outin the claims.

in the accompanying drawings forming port et this specification, Figure1 is a. side elevation. of the abutting ends of carrier sections, withmy invention applied thereto, ,u 2 is e similar View of one end sectiondetached from the other one, F ig. 3 is a view, partially in section,showing the construction of one member of the coupling, 4 is e sectionalview on the line -w of Fig. 2, Fig. 5 is an. end View of one of thesections and of the coupling applied thereto, Fig. 6 is a detail View ofone of the coupling members detached from the carrier.

ln the drawing, 2 represents the abutting rails of the carrier sectionswherein the rollrs 3 are mounted on rods 4t. The abutting ends of therails 9. are provided With recesses fi end yokes 6 are pivoted et 7 tothe rails in the rear ot seid recess. These yokes comprise side barsadapted to straddle the ends of the rails and cross bars or bridges 8and 9 between the side bars or rails. The bridge 9 projects above theside bars in position to Contact with the rail at the upper edge of thetherein and form a stop for limiting the upward swinging movement of theyoke. ber also may rest upon the Wall @ottoni oi' the recess, es shownin Fig. limit the downward movement of the Q yoke. lo, :i socket llbeing formed between the bars S and 9 so that when the members of thecoupling are brought together the de- 'fhe ber 8 hes a dependingextension.

pending portion 10 of one coupiing will drop into the socket l1 in theother coupling' member and lock the parts securely together as shown inFig. l. t Will be understood that the rails are tilted out ofelirmme'nt` with. one another to ellovv the coupling members to bejoined together and when in this position the cross ber 8 will beer onthe edge of the rei-l at the top of its recess and the cross bar 9 Wili'beer on the edge of theV rail at the'bottoni of its recess, therebypreventing separation of the coupling members aeelong as the rails 'outthe carrier ore infalinement vvith one another. When the rails aretilted upwardly then thev coupling members may be disengaged.

An important feature of this coupling device lies in the tact that themembers of the couplings are interchangeable and no fitting oradjustment is required.

I do not-.limit myself to the details of the construction herein shownand described, as 1t 1s obvious the same may be varied 1n manyparticularsv Without departing from my invention.

I claim as my invention 1. The combination, with the abutting railsprovided With recessed ends, of yokes pivoted on -said ends and havingsockets therein and cross bars bridging said sockets, each yoke having aprojection to enter the socket of the other yoke, and the cross bar ofone yoke bearing on the rail at the .top of its recess and the cross barof the other yoke bearing on the rail at the bottom of its recess,whereby When the mils are in alinement their abutting ends will belocked together.

2. The combination, with abutting rails, of interchangeable,interlocking coupling members pivot'ed on said rails, each, wuplingmember having a socket to receive the other coupling member, and bothcoupling mem` bers having means for locking them against prematureseparation. 3. The combination, with rails having abutting ends, ofcoupling members pivoted thereon, each member having a socket to re-vesv 4.
